Sangay (Ecuador): VAAC Washington reports pilot observations of ash emissions to 25,000 ft (7.5 km) altitude on 22 February. Since the volcano is very remote and one of Ecuador's most active, it is fair to assume that it might be in a state of elevated activity.

White Island (New Zealand): Strong continuous volcanic tremor has returned and is now higher than ever, mixed with earthquakes. No unusual activity is visible at the surface.

This information is seriously outdated and not complete, that's quite fresh official report [link to info.geonet.org.nz] Over the weekend the style of activity at White Island changed: the active vent began producing ash. The island was visited today and the ash emission has ceased, being replaced by steam and gas explosions from the active vent.

The level of volcanic tremor has increased, associated with the reappearance of fluids in the vent area. This change in activity is consistent with the level of unrest we have seen over the last month at the island...GNS volcanologist Brad Scott who visited the island today commented “the unrest continues and we continue to see small scale explosive events. Larger explosive eruptions can occur at any time with little or no warning....

[link to www.wired.com] Stunning Lava Fountains From Italy’s Etna..During the night of Feb. 23 (Saturday), the volcano unleashed a remarkable explosive volley, producing lava fountains that towered 800 meters over the crater on the southeast slopes of the volcano...The record for historic (and confirmed) lava fountain height is the 1986 eruption of Izu-Oshima in Japan that topped out at ~1,600 meters. When Tarawera erupted in 1886, the lava fountains in that basaltic eruption were estimated to be as tall as 2,000 meters (2 kilometers)* — that’s ~6,561 feet or 5.25 Empire State Buildings worth of lava fountain. The eruption of Tarawera did not have any geologists to accurately measure the height of the fountain, so the 2,000 meters height is based on local people’s recollection of the eruption. However, 2,000 meters isn’t unreasonable based on the eruptive rate and gas content of the Tarawera basalt. To take it even higher, the lava fountains from the 1779 eruption of Vesuvius were thought to have reached 3 kilometers (9,800 feet)!...

Boris Behncke • 2 hours ago...The tallest lava fountain ever seen (and photographed) at Etna was on 4 September 1999 and was *at least* 2000 m tall (the crater was the Voragine, one of the four summit craters). That means it was considerably taller than Izu-Oshima's 1986 fountains.

Secondly, the cone seen in the photograph has grown during the entire full set of 30 lava fountains since January 2011. By April 2012 it was about 200 m tall, and the amazing thing is it had grown during a combined 50 hours of lava fountaining, which indeed is a world record...

brucestout Boris Behncke • 6 hours ago.....or perhaps to phrase the question more simply: is the gas content of the magma entering the system more or less constant or does it vary? And does this variation explain the different phases or, conversely, are the phases merely a variation due to the eruption dynamics (foaming/degassing -> effusive activity).

excellent question!

question remain unanswered, and even excellent explanations about mechanism of origin of lava fountains at wired.com (above cited)do not add clarity of. found here year ago interesting comment with Etna description, history and risks

...The main problem of Etna in the fact that it has no direct consequences of the eruption depends on its strength and that's why.Etna Volcano amazing - both the shield volcano and built on its top stratovolcano. I'll tell you the well-known platitudes, which are everywhere found in his descriptions. Who is more dangerous and are considered as a shield to the eruption of the large number of cracks on the slopes and sides of craters because they are lower, closer to human settlements and when they poured out more lava (whereas in the higher craters and lava is far less does not apply). But just know that in the history of the most severe consequences of its eruption brought the collapse of slopes and a bore explosive. The fact is that except for the fact that it and the stratovolcano and shield, Etna, plus time and a huge caldera - it consists of a large number of growing on each other buildings with each of them - on the basis of their common patterns of calderas - sooner or later must come down. Amazingly complex system! And out of this just turns out that may not even be a very large eruption could potentially be disastrous - though exactly where it started, what type of will take place and what will be happening at the same time with every part of this beautiful monster individually and collectively .Uf.I'm sorry so many words only to explain why me disturbs new cracks on the slopes : new cracks means more possibilities of colapses, caldera type events, etc I guess. A large eruption would cause such an effect, or perhaps it is ordinary, what we often see in Etna, this one does not know in advance that bad. However many researchers in recent years noted with alarm that the Etna significantly alter a well-known to us for the past three centuries the type of activity. Let's watch!

my 5 cents. we are seeing though tumultuous, but very short paroxysms with fountain lava. ie the amount of emitted lava light and gases under high pressure a lot. so much in the body big cavities. what it may bring, knowing the history of Mount Etna?
